This invention relates to improvements in hposition parallel the head frame so that the l `bed as a whole will occupy but a smallspace when not in use. i A V i r A. further objectof theinvention is to provide an improved counter-balancing mechanism for the bedframe, which will hold the same in any oneof a number of angular` posi-` tions and which mechanism is so: arranged that it presents no interference` to the bedding and pillows and will `not lose its counterbalancing eiect through a long and continued use. u

Still another object cf the invention is to` provide a foot end structure of the bow end kindwhich will automatically fold against the bed frame when the same is being swung up Award and which will automatically open into substantially `its `normal upright position when `the bedwframe. is swung down into its position `for use. A Jfurther object4 of the .invention is to 3o provide such a bed `whereinthe number of parts employed are reduced to a minimum, thus not only reducing the cost thereoi1l but also simplifying its operation and enhancing its appearance. These objects of the invention,together with others, as well as the many advantages thereof will more fully appear as I proceed with my specification.

Means for providing for counter balancing the bed frame in its movement and such means are as follows. Pvotally connected to each trunnion 2Oa is one end of a tension arm 23, the other end of which is pivotally connected to the associated end of a second tension 'arm 24 by a pin 25. The other end of the last mentioned tension arm is pivotally mounted Qn a rearwardly extending trunnion 26 of a bracket plate 27 fixed to the rear sido of each side member 2b of the head frame 2, as best shown in Fig. 7, at a point just above the top end of thesecondary frame.

foot'frame `ivillfs'wini,T inv close to the bed .frame when the 'same' is swung upwardly into its folded position so as to come within the vertical plane ofthehead end of theb'ed as indicatedbylthedotted line in Fig. Q. Againythis construct-ion permits thetop end othe foot' frame tovposition ,itself Vbelow the Aframe member 6 as' besty shovvn in Asaid figure, ,so -thatfthe ybed as la whole may be swung through the door o pel'iing. i

Assume that the bed frame is in its normal horizontal position as shown in full lines in F ig. 1 and it is desired to swing the bed frame into a vertical position for the purpose well known. The operator imparts an upward lift on the foot frame when the rollers 18 will roll down the side members 2b of the head frame 2 and the links 22 will swing` forwardly as the rollers move downwardly. VlThen the bed frame has reached the intermediate position shown by the dotted lines in Fig. 1 the pivotal connection 22 of the links 22 with the side frame member has reached the limit of its downward swing and the roller 18 has reached a position wherein it is in substantially the same horizontal plane as said pivotal connection. Thus far, the roller has moved a distance greater than that of said pivotal connection 22a and as the roller passes this horizontal plane and continues in its downward movement, said pivotal connection is moving upwardly again until the bed frame reaches its vertical position, the rollers 18 and pivotal connections 22 moving at substantially the same speed and through about the same distance. Thus, in the movement of the bed frame from the horizontal to the vertical movement, the pivotal connection 22a will swing to its limit in one direction and then a part way back again. ln the downward movement of the roller, the tension arms z3-24 which are locatedl to the rear of the panel, will open up against the normal contractile tendency of the spiral springs 2S and will counterbalance the weight of the bed frame so that when the bed frame is in its vertical position, said arms will approach parallelism. It is apparent that the above mentioned construction provides a shifting fulcrum connection between the bed frame and head frame. i

In this upward movement of the bed frame, the foot frame 3 will swing about its pivotal axis 3() and when said bed frame reaches its vertical position, the foot frame will eX- tend substantially parallel thereto, as best shown in Fig. 6.

In the downward movement of the bed frame the pivotal connection 22a will first move downwardly and the roller 1B will move upwardly at about the same speed until they reached substantially the same horizontal plane when said pivotal connection will move upwardly. the roller 18 also moving upwardly. As the roller moves upwardly. the tension arms will. approach each other and this approach is resisted by the springs carried by said arms which, of course, will prevent the rapid falling,r of the bed frame under its own weight after leaving said ver tical position. During this downward movement of the bed frame, the foot frame will hang in an angular position inclined from the perpendicular, under the action of gravity with the bottom ends of the feet of the foot frame directed toward the head end of the bed. However, as the bed frame approaches its horizontal position, it is only natural for the operator to egraspv the top edge portion of the foot frame to bring the bed frame to its horizontal position. During this last part of the movement of the bed frame, the foot frame is, without appreciable elfort, swung about its pivotal connection with the bed frame until the brackets on the foot frame engage the foot end of the bed frame when the foot frame is arranged at a. right'angle to the bed frame. l/Vhen the bed frame is in its horizontal position, the foot frame rests on the floor in its upright position. The construct-ion of the foot frame is such that it will. freely pass the corners of the bed frame and pivoting the foot frame in this manner cuts down the combined height of the bed frame and foot frame when the bed frame is in its vertical position. Jagain this pivotal connection will permit the foot frame to more closely approach the bed frame when the same is in its vertical position. In this manner much space both vertically and horizont-ally is saved, and the saving of space occupied by the bed when not in use, is indeed a matter of importance and is a determining factor in installations.

My improved bed has many advantages. It comprises but a small number of parts which are strong and rigid and may be assembled by unskilled workers without in any manner detracting from the eflicient operation of the bed. lt is counterbalanced at all times so that there is no possibility ofthe bed frame swinging downwardly under its own weight to the danger of the operator when bringing the bed frame into its horizontal posit-ion. The bed frame cannot bind in its movement because the guides will yield so that the rollers thereof will follow any unequalities in the parts with which they engage. rlhe counterbalancing arms are concealed by the panel on the head frame and which panel also prevents the bed clothes from engagement with said arms.

lVhile in describing my invention, I have referred to certain details of mechanical construction, as well as form and arrangement of parts, the same is for purpose of illustration only so that l do not wish to limit myself thereto except as maybe pointed out in the appended claims.

I claim as my invention:

1. A folding bed embodying therein, a head frame including a side member, a bed frame spaced inwardly from said side member, a bracket carried by the bed frame, a shaft mounted in said bracket, and spaced to the rear of the said head frame, a flanged roller on said shaft disposed outside of said side member and engaging one corner therelll-5 of, and means acting upon said roller` to cause theflange to yieldingly engage Said corner of Said side member.

2. A folding bed embodying therein, a head frame including a side member, a bed frame spaced inwardly from said side meinber, a bracket carried by the bed frame, a shaft mounted in said bracket and Idisposed to the rear of said side member for endwise movement toward and away from the side member, a flanged roller on said shaft engaging one corner of said side member and means acting on said shaft to yieldingly move the same endwise toward the side member to u hold the roller l'ange in contact With said corner thereof.

In testimony whereof, I have hereunto set my hand, this 27th day of July, 1925.
